Tuktuk the Explorer

A goblin who is worth more dead than alive: the body that comes down is a 1/1 with haste, but the value sits entirely on the back end, where killing it hands you a 5/5 artifact creature token that has none of the original's fragility. The design inverts the usual death-trigger calculus. Most "dies" payoffs ask you to sacrifice something with a body still on board; here, removal aimed at the small creature simply trades one threat for a much larger one, which means the opponent's interaction either rots in hand or feeds the upgrade. Board wipes and combat damage do the same favor. The token is its own legendary creature with a different name, so the legend rule never collides the two: you can field the explorer and the returned golem at once if the first one comes back some other way. The split into two named permanents is also what lets the golem stick around as a colorless artifact, dodging the red-hating answers that would have caught the original. It is a small, self-contained lesson in building a creature whose death is the upside rather than the cost, and it reads as a goblin flavor joke that happens to be mechanically sound: send the little one ahead to explore, and what comes back is bigger and made of metal.
